Best Water Heaters of 2025

"This is my third time purchasing these tanks. I bought one two years ago for my off-grid solar, and it's still going strong. I decided to buy two more: one to replace my 40-gallon electric heater and another as a spare for prepping. I don’t understand some of the negative reviews; it’s a 7-gallon hot water heater after all. While I can’t get a 20-minute hot shower, I enjoy 10 to 12 minutes of pretty warm water. It uses less than one-third of the electric my old heater did, and I can run it on solar or a small generator. My only issue was with one that was marked as like new, but I saved $160 buying two, so I'm satisfied. I highly recommend these water heaters!"

"We recently bought a ranch house and encountered a crawl space with over 60 feet from the tankless heater to the master bathroom. It took 1.5 minutes for hot water to reach the tap, which wasn't ideal for my wife. After researching, I chose this water heater. I had a smooth installation experience, though I had to drill a hole for the cord. The heater works perfectly—hot water at 111 degrees F—and flows for two minutes. We’re very pleased and plan to order another for the guest bathroom!"

"This unit has been fantastic for our farm bathroom, providing hot water where we previously had none. I'm very happy with this purchase and would buy it again."

"I live in a mobile community and recently had to replace my old water heater that sprung a leak. After shopping around, I found this unit to be an excellent choice. It's easy to install and works like a charm. The endless hot water is a game changer for me. I can enjoy insanely hot showers without worrying about running out. Plus, I've saved on my power bill! I can't believe I found such a cost-effective solution that performs so well."

"Switching from a traditional water heater to this tankless model was surprisingly smooth. I was worried about performance issues, but this heater exceeded my expectations. I love the flexibility it gives me in managing water temperature. With a pressure-enhancing shower head installed, I'm getting all the hot water I need without having to deal with the usual cold-water adjustments. Best of all, I'm saving money on my electric bill!"

"استخدمته بدل السخان المركزي في ينبع، كان تركيب السخان سهلاً جداً. حتى الآن، أداءه ممتاز بعد شهرين من الاستخدام. سخان موفر للطاقة، وأنا سعيد جداً بهذا الاختيار."

"I bought this to replace a standard tank water heater. It was easy to install and worked well with my existing vent. I did have to purchase a water polisher and a condensate neutralizing capsule, which added to the cost, but it was manageable. I also had to adjust the flow rate settings for my washing machine, but that was straightforward with the manual."

"I absolutely love this water heater! Water heats up almost instantly, and I no longer have to pay for propane. I wish I had known about it sooner. My plumbers were skeptical, but after finding a good installer, I found that this unit not only looks great on the wall but also freed up space in my basement. Although it cost more than a tank, it's worth every penny including installation."

"I replaced my old tank with this unit in under six hours. It provides all the hot water my family needs and freed up storage space. I am really pleased with my decision."

"I recently had the Stibel Electron Tempera 20 electric tankless water heater installed in my two-story home, and I couldn't be happier with the results. The installation took about four hours, and the unit's performance has exceeded my expectations. It's impressively quiet and its space-saving design is a game-changer. I tested it by running two showers simultaneously for an extended period, and there was no interruption in hot water. The temperature control is precise, ensuring that I get the hot water I desire without any fuss. Investing in this unit has been a wise decision for my household."

"For five years, I lived with a 75-gallon gas hot water heater. I decided to switch to electric for our future solar roof installation. I went with the 29kW unit as there are only two of us. We enjoy unlimited hot water, and the accurate temperature control is fantastic. I installed it beneath the kitchen for quick access, eliminating the long wait for hot water. The only downside is during a power failure I won't have hot water, but I haven't lost power in five years. Overall, the unit has been flawless and just works."

"Hasta ahorita he tenido un mes este producto y ha funcionado a la perfección. Requiere una instalación eléctrica especializada, pero el flujo de agua es constante y alto. No ocupa nada de espacio y puede estar en el interior de la casa en un espacio pequeño. Además, es muy silencioso."

"I specifically bought this for my senior dog, and I needed a way to give her a bath even in the cold. After researching various camping showers, I chose this one based on YouTube reviews. It works great for the heat I need, reaching about 80 to 90 degrees. The water flow is fantastic, and it doesn’t make loud noises. Just be careful where you mount it, as the top can get extremely hot!"

"This is my second Camplux shower, and I’m really pleased with it. The first one had battery issues, but the new model has been fantastic—one set of batteries lasted an entire trip! The water gets hot quickly and has adjustable flow rates. The setup is versatile, allowing for various attachments, which is a big plus!"

"After a month of using this outdoor shower, I noticed some issues with the hose and handle, which eventually burst. But I was impressed by the customer service; they reached out to apologize and sent me a replacement unit. The new one has been working well, although I've had minor issues with the handle. Overall, I’m happy with its utility and performance!"

"I'm really impressed with this mini tank water heater! It provides instant hot water on demand, so no more waiting for hot water at the sink. The 1.6-gallon tank is perfect for quick tasks, and the adjustable temperature control lets me set it just how I like. The compact design fits nicely in my garage apartment, and the safety features give me peace of mind. Overall, it's a reliable and efficient solution for getting hot water quickly. I highly recommend it!"

"This water heater is incredibly efficient. It heats water quickly and maintains a consistent temperature. I've been using it for a few weeks now, and it has been very reliable. It's perfect for my kitchen sink and saves me a lot of time waiting for hot water."

"I was pleasantly surprised by how easy it was to install. The instructions were clear, and I didn't need any professional help. It's a great option for those who want a quick and easy solution for hot water in their kitchen or bathroom."

"I purchased this off Amazon warehouse for a discounted price of $171, and after tax and shipping, it came out to $188. This is drastically lower than the $600 plus tax offered by Home Depot or Lowe's. When my water heater went out, I found this Rheem tankless water heater. I had installed one of these at a friend's house, and while it had its issues, this time I had no problems at all. It was easy to set up and works just as intended. I'm very happy with it!"

"We installed this water heater when we bought our new house in February 2022. I was a bit nervous since I had never used a tankless model before, but it has worked flawlessly for our family of 5. We've used multiple hot water sources at once, and there have been no issues. I'm thrilled with the performance of this system!"

"I was eager to get this product as a gift for my home. However, it turned out to be one of the worst products I've ever bought. It doesn't heat water consistently, leading to bursts of hot and cold water. We can't even take baths anymore, which was the main reason for purchasing it. Customer support was unhelpful, and I regret upgrading my appliance. I just want to take a bath at home again!"

"I waited a couple of weeks to share my experience. Installation was a breeze and I've had no issues so far. We have plenty of hot water to run our shower, dishwasher, clothes washer, and sink all at the same time!"

"This is my sixth Camplux product, and I couldn't be happier. Customer service is top-notch, and I've had a couple of minor issues resolved swiftly. I will definitely continue to purchase from Camplux and highly recommend their products!"

"After installing this water heater, it produced hot water in under two minutes. It's really fuel efficient compared to my old one, and the installation was straightforward, taking about 45 minutes with everything included."

"I found the installation to be straightforward and the delivery crew was incredibly helpful and polite. After plumbing, we only had to adjust the temperature slightly. It's been running great with no problems!"

"Switching from an electric water heater has reduced my electric bill by $50 a month. The water temperature is excellent, and it's surprisingly quiet. I'm really glad I made this upgrade."

"I really appreciate the design and efficiency of this heater. It only uses 120V and the instructions were very clear. After four months, it has performed excellently, managing to supply hot water for our 3-bedroom home without any issues."

"I found it very easy to install. The connections were straightforward, but the most challenging part was setting up the 115v outlet beneath the sink. Despite its size, having warm water is well worth it."

"Living in Florida, I’ve purchased three of these units for two bathrooms and the kitchen. They deliver almost instant hot water at all faucets, which is a big relief."

"I was excited to use this water heater, but it didn't work at all. Installation was simple, but when I plugged it in, there was no power. As a licensed electrician with decades of experience, I've installed many water heaters, but this one was disappointing."
